What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
My understanding is that your sub-users have an access to your account password. Please take note that you don't need to share your login credentials to your sub-users.
The purpose of having a sub-user is to share forms by viewing the submissions and editing the forms. They can access the shared forms in the shared folder.
It means that they don't need to log in using your credentials. Please check this user guide: https://www.jotform.com/help/232-How-to-Share-Forms-with-a-Sub-account-User.
Hope that helps. If you have any questions, let us know. Thank you.
